ABSTRACT

Development of exposed photographic silver halide emulsion is described wherein development occurs by means of an organometallic complex of a metal capable of changing its valency and an aliphatic aminocarboxylic acid containing at least one mono- or di(carboxyalkyl)aminoalkyl group and at least one hydroxyl group, or a water-soluble salt of the chelating compounds.
